World Memo
- Final Selection requirement
Becoming a Demon Slayer requires attending the Final Selection held on Mount Fujikasane. The trainer alone decides whether a student may enter.
- Blood Demon Art spells
Some kinds of demons possess spells called Blood Demon Art, which grant them supernatural abilities.
- Blood Demon Art naming convention
Demon techniques are classed as Blood Demon Arts and given a name, such as Scent of Illusory Blood, Visual Dream.
- Demon Slayer rank and pay
Demon Slayers can climb the ranks, and higher rank brings better pay.
- No speaking before Hashira
Members must not speak in the presence of a Hashira; Kakushi enforce this by pressing the offender's head into the ground.
- Butterfly Mansion as rehabilitation site
Injured Demon Slayers recuperate at the Butterfly Mansion under a head caretaker and helpers, who administer their medication. Recovered patients then go through a rehabilitation program of three stations: stretching, reflex training with medicated water cups, and full-body training played as tag.
- Recovery from partial transformation
A person whose body has partly begun to change, such as an arm that stays altered, can avoid lasting effects by taking the medication and getting plentiful sunlight. Without them the changes may not return to normal.
- Kasugai Crow relays messages
Demon Slayers receive messages through their assigned Kasugai Crow.
- Breathing style names must be distinct
Each Breathing Style has its own name, and styles must not be misnamed as one another; Fire Breathing is distinct from the more familiar Flame Breathing.
- Twelve Kizuki demon rank
The Twelve Kizuki are a group of elite demons that serve directly under Muzan.
Members of the Twelve Kizuki have a number engraved on their eyeballs; a demon lacking this eye marking is not a true member, regardless of claiming the rank.
A rank can be lost: Kyogai, once Lower Rank Six, hoped to win his place back by devouring Marechi blood.
- Nine strongest swordsmen
The Hashira are the nine most powerful swordsmen in the Demon Slayer Corps.
Clue Board
- Muzan's feared hanafuda-earring enemy (Episode 8)
Muzan suddenly becomes terrified while alone, recalling a past figure standing before him, a feared enemy who raised a sword while wearing hanafuda earrings. The identity of this enemy is not revealed.
- Marechi blood term (Episode 12)
Kyogai calls Tanjiro 'Marechi', which Tanjiro's crow explains refers to someone with rare blood worth fifty or a hundred people if devoured; whether Tanjiro is Marechi is left open.
- Mould-like smell at claw attack (Episode 13)
Tanjiro senses a mould-like smell that appears whenever Kyogai uses the claw attack, a cue he uses to read the attacks, though its source and meaning are not explained.
- Source of the rattling sound (Episode 15)
A strange rattling sound travels through the air, unsettling Tanjiro; the surviving Demon Slayer says the massacre began after this sound, and its source is unexplained.
- Tanjiro unburned by Nezuko's flames (Episode 20)
Rui wonders why Tanjiro was not burned by Nezuko's flames while his threads were, a question left unexplained.
- Nezuko's restraint (Episode 21)
Nezuko spends energy healing her wounds and fighting while resisting the urge to kill Tanjiro for food, and Giyu notices she is different from other demons.
The Demon Slayer girl notices that Nezuko only evades her slashes and does not attack back, which she sets aside without pursuing.
- Unexplained event surprising Muzan (Episode 22)
The Master believes something happened to Nezuko that even surprised the Demon Progenitor, but the nature of that event is not revealed.
- Kanao's silence toward the Kakushi (Episode 23)
Kanao ignores the female Kakushi's request for permission to enter and does not answer a second question. The reason for her silence is not given.
- Possible Upper Rank demon (Episode 24)
Kyojuro suspects the demon that killed several Demon Slayers could be a Twelve Kizuki, possibly even an Upper Rank, but no identity is confirmed.
- Kanao's Hashira-like scent (Episode 24)
Tanjiro notices Kanao has a scent similar to the Hashira, a hint about her standing that is not yet explained.
- Hinokami Kagura origin (Episode 25)
Shinobu knows nothing of Hinokami Kagura and only suggests Tanjiro's father may have used a different breathing style, Fire Breathing, which is not the same as Flame Breathing; the nature of Hinokami Kagura remains unexplained.
- Nezuko's words while asleep (Episode 25)
Nezuko says "I know you can do it, Big Brother" while apparently still asleep, so it is unclear whether she is truly aware of her surroundings.
Deduction Board
Facts
- Inability to make choices
Shinobu finds Kanao unable to make choices and not eating until told to, even when starving.
- Shinobu knows nothing of Hinokami Kagura
When Tanjiro asks Shinobu about Hinokami Kagura, she knows nothing about it.
- Shinobu knows nothing of Fire Breathing
When Tanjiro asks about Fire Breathing, Shinobu gives the same response.
Evidence
- Coin flip
Kanao takes a coin from her pocket, flips it, and catches it, looking at the flipped side while reminiscing about her past.
- Coin given by Kanae
Kanae gives Kanao a coin to help her decide, and Kanao stares at it later while watching the trio train.
- Father's influence described to Shinobu
After Tanjiro tells Shinobu what happened to him and how his father influenced him, she responds to the question about Hinokami Kagura.
Inferences
- Sleep restores Nezuko's stamina
Nezuko sleeps for whole days at the mansion, and Tanjiro believes she is simply regaining her stamina.
- Coin as a tool for choice
The coin is used to help Kanao decide, which links it to her inability to make her own choices.
- Father may have used Fire Breathing
Shinobu suggests Tanjiro's father perhaps used Fire Breathing, which she distinguishes from the more familiar Flame Breathing and warns must not be confused with it.
Suspicions
- Something about Nezuko surprised Muzan
The Master believes something happened to Nezuko that even surprised Muzan
- Possible love-driven change
Kanae says that given a chance, a person's soul will open up, and that Kanao can change if she falls in love.
- Flame Hashira may know more
Shinobu says Tanjiro could perhaps ask the Flame Hashira, who is away on a mission, so the answer remains open.

Ability Table
| User | Ability | Description |
|---|---|---|
| Tanjiro Kamado | Total Concentration Breathing | A breathing technique taught by Makomo that accelerates blood circulation and heart rate and raises body temperature, letting the user match a demon's strength while remaining human. It works by expanding lung capacity to flood the body with air, strengthening bones and muscles. Refined into a sustained 'Constant' form that can be maintained throughout the day, including during sleep, greatly boosting stamina; the user must push hard to hold it at first but eventually keeps it up without slowing down. |
| Nezuko Kamado | Blood Demon Art, Exploding Blood | Drops of her blood on the threads glow and are ignited, burning the threads away along the webs. |
| Tanjiro Kamado | Hinokami Kagura, Dance | A breathing pattern recalled from his memories of his father's ceremonial kagura, which ignites his Water Breathing into fire; used in the Dance form to slice through the blood threads. |
| Nezuko Kamado | Demon wound healing | As a demon, Nezuko heals her own wounds by spending her energy, even while fighting, and she must resist her urge to eat humans while doing so. |
| Tanjiro Kamado | Opening Thread | A scent Tanjiro detects and follows to align the path of his sword with its target. |
| Tanjiro Kamado | Water Breathing, Tenth Form: Constant Flux | Used to parry the threads by gathering momentum in each swing, slicing through the blood threads and giving him the drive to press the attack. |
| Inosuke Hashibira | Beast Breathing, Seventh Form: Spatial Awareness | Plants both blades in the ground, crouches and spreads arms to scan the surrounding forest, detecting trees, vegetation and the landscape far around him in order to locate a demon. |
| Inosuke Hashibira | Beast Breathing, Third Fang: Devour | A self-taught breathing technique. He slashes off the demon's arms, then lunges forward with both blades to slice off its head. |
| Tanjiro Kamado | Water Breathing, First Form: Water Surface Slash | Used to decapitate the morphed demon, killing it. |
| Tanjiro Kamado | Water Breathing, Fourth Form: Striking Tide | Used to slash two demons in one stroke after he finds the Opening Thread. |
| Tanjiro Kamado | Water Breathing, Second Form: Improved, Lateral Water Wheel | An improved version of the Second Form, used to decapitate the Arrow Demon despite the heavy weight of the combined attack. |
| Tanjiro Kamado | Water Breathing, Second Form: Water Wheel | Used to counter an incoming attack from behind by turning around and cutting. |
